equity securities which are classified as available-for-sale. Available-for-sale
securities are carried at fair value, with unrealized gains and losses reported
as a separate component of participants' capital. The Trust recorded an
unrealized gain on available-for-sale securities of $3,175 during the six months
ended June 30, 1999 that is included as a separate component of participants'
capital.

     At June 30, 1999, the Trust had $1,177,334 invested in federal agency
discount notes and reverse repurchase agreements secured by U.S. Treasury Bills
or interests in U.S. Government securities. Such cash includes $500,709 which is
classified as Restricted Cash and represents funds designated to pay a special
cash distribution to Class A Beneficiaries in conjunction with the settlement of
the Class Action Lawsuit referred to in Notes 8 and 9.


NOTE 3 - REVENUE RECOGNITION

     Rents are payable to the Trust monthly, quarterly or semi-annually and no
significant amounts are calculated on factors other than the passage of time.
The leases are accounted for as operating leases and are noncancellable. Rents
received prior to their due dates are deferred. In certain instances, the Trust
may enter primary-term, renewal or re-lease agreements which expire beyond the
Trust's anticipated dissolution date. This circumstance is not expected to
prevent the orderly wind-up of the Trust's business activities as the Managing
Trustee and the Advisor would seek to sell the then-remaining equipment assets
either to the lessee or to a third party, taking into consideration the amount
of future noncancellable rental payments associated with the attendant lease
agreements. Future minimum rents of $1,341,566 are due as follows:

NOTE 4 - EQUIPMENT

     The following is a summary of equipment owned by the Trust at June 30,
1999. Remaining Lease Term (Months), as used below, represents the number of
months remaining from June 30, 1999 under contracted lease terms and is
presented as a range when more than one lease agreement is contained in the
stated equipment category. A Remaining Lease Term equal to zero reflects
equipment either held for sale or re-lease or being leased on a month-to-month
basis. In the opinion of EFG, the acquisition cost of the equipment did not
exceed its fair market value.

</TABLE>

     The Trust's equipment portfolio includes certain assets in which the Trust
holds a proportionate ownership interest. In such cases, the remaining interests
are owned by EFG or an affiliated equipment leasing program sponsored by EFG.
The Trust and each affiliate individually report, in proportion to their
respective ownership interests, their respective shares of assets, liabilities,
revenues, and expenses associated with the equipment. At June 30, 1999, the
Trust's equipment portfolio included equipment having a proportionate original
cost of $5,467,490, representing approximately 59% of total equipment cost.

     At June 30, 1999, the cost and net book value of equipment held for sale or
re-lease was approximately $880,000 and $2,000, respectively. The Managing
Trustee is actively seeking the sale or re-lease of all equipment not on lease.


NOTE 5 - INVESTMENT IN KIRKWOOD

     On May 1, 1999, the Trust and three affiliated trusts (collectively the
"Trusts") and another affiliate formed EFG/Kirkwood Capital LLC ("EFG/Kirkwood")
for the purpose of acquiring preferred and common stock interests in Kirkwood
Associates Inc. ("KAI"). The Trusts purchased Class A Interests in EFG/Kirkwood
and the other affiliate purchased Class B Interests in EFG/Kirkwood. Generally,
the Class A Interest holders are entitled to certain preferred returns prior to
distribution payments to the Class B Interest holders. KAI owns a ski resort, a
local public utility, and significant land which is held for development. The
resort is located in Kirkwood, California and is approximately 30 miles from
South Lake Tahoe, Nevada. The Trust's ownership interest in EFG/Kirkwood had a
cost of $1,212,000, including a 1% acquisition fee ($12,000) paid to EFG. At
June 30, 1999, the Trust owed $450,000 to an affiliate related to this
transaction which is included in Accrued Liabilities - Affiliates on the
accompanying Statement of Financial Position at June 30, 1999. This amount was
paid in July 1999.

     All rents and proceeds from the sale of equipment are paid directly to
either EFG or to a lender. EFG temporarily deposits collected funds in a
separate interest-bearing escrow account prior to remittance to the Trust. At
June 30, 1999, the Trust was owed $140,606 by EFG for such funds and the
interest thereon. These funds were remitted to the Trust in July 1999.

     Administrative charges represent amounts owed to EFG, pursuant to
Section 10.4(c) of the Trust Agreement, for persons employed by EFG who are
engaged in providing administrative services to the Trust. Administrative
charges and reimburseable operating expenses for the six months ended June
30, 1999 include adjustments for 1998 actual costs of approximately $27,000
and $19,000, respectively.

NOTE 7 - NOTES PAYABLE

     Notes payable at June 30, 1999 consisted of installment notes of $720,206
payable to banks and institutional lenders. The notes bear interest rates of
5.7%, except for one note which bears a fluctuating interest rate based on LIBOR
(4.99% at June 30, 1999) plus a margin. All of the installment notes are
non-recourse and are collateralized by the equipment and assignment of the
related lease payments. Generally, the installment notes will be fully amortized
by noncancellable rents. However, the Trust has a balloon payment obligation of
$282,421 at the expiration of the primary lease term related to its interest in
an aircraft leased to Reno Air, Inc. The carrying amount of notes payable
approximates fair value at June 30, 1999.

     The annual maturities of notes payable are as follows:

NOTE 8 - LEGAL PROCEEDINGS

     On or about January 15, 1998, certain plaintiffs (the "Plaintiffs") filed a
class and derivative action, captioned LEONARD ROSENBLUM, ET AL. V. EQUIS
FINANCIAL GROUP LIMITED PARTNERSHIP, ET AL., in the United States District Court
for the Southern District of Florida (the "Court") on behalf of a proposed class
of investors in 28 equipment leasing programs sponsored by EFG, including the
Trust (collectively, the "Nominal Defendants"), against EFG and a number of its
affiliates, including the Managing Trustee, as defendants (collectively, the
"Defendants"). Certain of the Plaintiffs, on or about June 24, 1997, had filed
an earlier derivative action, captioned LEONARD ROSENBLUM, ET AL. V. EQUIS
FINANCIAL GROUP LIMITED PARTNERSHIP, ET AL., in the Superior Court of the
Commonwealth of Massachusetts on behalf of the Nominal Defendants against the
Defendants. Both actions are referred to herein collectively as the "Class
Action Lawsuit." The Class Action Lawsuit was divided into two sub-classes on
March 22, 1999.

     On May 26, 1999, the Court issued its Order and Final Judgment approving
settlement of the Class Action Lawsuit with respect to claims asserted by the
Plaintiffs on behalf of the sub-class that includes the Trust. Claims involving
the second sub-class, not including the Trust, remain pending. As a result of
the settlement, the Trust declared a special cash distribution of $500,709,
including legal fees for Plaintiffs' counsel of $26,913, that was paid in July
1999. In addition, the parent company of the Managing Trustee, Equis II
Corporation, agreed to commit $1,126,595 of its Class B Capital Contributions
(paid in connection with its purchase of Class B Interests in July 1997) to the
Trust for the Trust's investment purposes. In the absence of this commitment,
Equis II Corporation would have been entitled to receive a Class B Capital
Distribution for this amount pursuant to the Trust Agreement, as amended. The
Trust's share of legal fees and expenses related to the Class Action Lawsuit,
including the fees for Plaintiff's counsel referenced above, is estimated to be
approximately $88,000, all of which was accrued and expensed by the Trust in
1998.

     In addition to the foregoing, the Trust is a party to other lawsuits that
have arisen out of the conduct of its business, principally involving disputes
or disagreements with lessees over lease terms and conditions. The following
action was resolved during the quarter ended June 30, 1999:

ACTION INVOLVING NATIONAL STEEL CORPORATION

     EFG, on behalf of the Trust and certain affiliated investment programs
(collectively, the "Plaintiffs"), filed an action in the Commonwealth of
Massachusetts Superior Court, Department of the Trial Court in and for the
County of Suffolk on July 27, 1995, for damages and declaratory relief against a
lessee of the Trust, National Steel Corporation ("National Steel"). The
Complaint seeks reimbursement from National Steel of certain sales and/or use
taxes paid to the State of Illinois in connection with equipment leased by
National Steel from the Plaintiffs and other remedies provided under the Master
Lease Agreement ("MLA"). On August 30, 1995, National Steel filed a Notice of
Removal, which removed the case to United States District Court, District of
Massachusetts. On September 7, 1995, National Steel filed its Answer to the
Plaintiff's Complaint along with Affirmative Defenses and Counterclaims and
sought declaratory relief, alleging breach of contract, implied covenant of good
faith and fair dealing, and specific performance. The Plaintiffs filed an Answer
to National Steel's Counterclaims on September 29, 1995. The parties discussed
settlement with respect to this matter for some time; however, the negotiations
were unsuccessful. The Plaintiffs filed an Amended and Supplemental Complaint
alleging further default under the MLA and filed a motion for Summary Judgment
on all claims and Counterclaims. The Court held a hearing on the Plaintiff's
motion in December 1997 and later entered a decision dismissing certain of
National Steel's Counterclaims, finding in favor of the Plaintiffs on certain
issues and in favor of National Steel on other issues. On May 11, 1999, the
parties executed a comprehensive settlement agreement to resolve all outstanding
issues, including reimbursement to the Trust for the disputed sales tax items
referenced above. This matter did not have a material effect on the Trust's
financial position or results of operations.

NOTE 9 - SUBSEQUENT EVENT

     In July 1999, the Trust distributed $500,709, including legal fees of
$26,913 paid to Plaintiffs' counsel, as a special cash distribution in
connection with the settlement of the Class Action Lawsuit described in Note 8
above.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.

     AFG Investment Trust B (the "Trust") commenced operations in 1992 and,
pursuant to its Trust Agreement, the Trust is scheduled to be dissolved by
December 31, 2003. The Trust was a Nominal Defendant in a Class Action Lawsuit
that was settled, with respect to the Trust and certain affiliates, in May 1999.
See Note 8 to the accompanying financial statements.

     Certain statements in this quarterly report that are not historical fact
constitute "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995 and are subject to a variety of risks
and uncertainties. There are a number of important factors that could cause
actual results to differ materially from those expressed in any forward-looking
statements made herein. These factors include, but are not limited to, the
collection of the Trust's contracted rents, the realization of residual proceeds
for the Trust's equipment, and future economic conditions.

YEAR 2000 ISSUE

     The Year 2000 Issue generally refers to the capacity of computer
programming logic to correctly identify the calendar year. Many companies
utilize computer programs or hardware with date sensitive software or embedded
chips that could interpret dates ending in "00" as the year 1900 rather than the
year 2000. In certain cases, such errors could result in system failures or
miscalculations that disrupt the operations of the affected businesses. The
Trust uses information systems provided by Equis Financial Group Limited
Partnership (formerly American Finance Group) ("EFG") and has no information
systems of its own. EFG has adopted a plan to address the Year 2000 Issue that
consists of four phases: assessment, remediation, testing, and implementation
and has elected to utilize principally internal resources to perform all phases.
EFG has completed substantially all of its Year 2000 project at an aggregate
cost of less than $50,000 and at a di minimus cost to the Trust. All costs
incurred in connection with EFG's Year 2000 project have been expensed as
incurred.

     EFG's primary information software was coded by a third party at the point
of original design to use a four digit field to identify calendar year. All of
the Trust's lease billings, cash receipts and equipment remarketing processes
are performed using this proprietary software. In addition, EFG has gathered
information about the Year 2000 readiness of significant vendors and third party
servicers and continues to monitor developments in this area. All of EFG's
peripheral computer technologies, such as its network operating system and
third-party software applications, including payroll, depreciation processing,
and electronic banking, have been evaluated for potential programming changes
and have required only minor modifications to function properly with respect to
dates in the year 2000 and thereafter. EFG understands that each of its and the
Trust's significant vendors and third-party servicers are in the process, or
have completed the process, of making their systems Year 2000 compliant.
Substantially all parties queried have indicated that their systems are Year
2000 compliant.

     Presently, EFG is not aware of any outside customer with a Year 2000 Issue
that would have a material effect on the Trust's results of operations,
liquidity, or financial position. The Trust's equipment leases were structured
as triple net leases, meaning that the lessees are responsible for, among other
things, (i) maintaining and servicing all equipment during the lease term, (ii)
ensuring that all equipment functions properly and is returned in good
condition, normal wear and tear excepted, and (iii) insuring the assets against
casualty and other events of loss. Non-compliance with lease terms on the part
of a lessee, including failure to address Year 2000 Issues could result in lost
revenues and impairment of residual values of the Trust's equipment assets under
a worst-case scenario.

     EFG believes that its Year 2000 compliance plan will be effective in
resolving all material Year 2000 risks in a timely manner and that the Year 2000
Issue will not pose significant operational problems with respect to its
computer systems or result in a system failure or disruption of its or the
Trust's business operations. However, EFG has no means of ensuring that all
customers, vendors and third-party servicers will conform ultimately to Year
2000 standards. The effect of this risk to the Trust is not determinable.

THREE AND SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO THE THREE AND SIX MONTHS
ENDED JUNE 30, 1998:

RESULTS OF OPERATIONS

     For the three and six months ended June 30, 1999, the Trust recognized
lease revenue of $346,650 and $670,391, respectively, compared to $589,802 and
$1,563,454 for same periods in 1998. The decrease in lease revenue from 1998 to
1999 resulted principally from lease term expirations and the sale of equipment.
The level of lease revenue to be recognized by the Trust in the future may be
impacted by future reinvestment; however, the extent of such impact cannot be
determined at this time.

     The Trust's equipment portfolio includes certain assets in which the Trust
holds a proportionate ownership interest. In such cases, the remaining interests
are owned by EFG or an affiliated equipment leasing program sponsored by EFG.
Proportionate equipment ownership enables the Trust to further diversify its
equipment portfolio by participating in the ownership of selected assets,
thereby reducing the general levels of risk which could result from a
concentration in any single equipment type, industry or lessee. The Trust and
each affiliate individually report, in proportion to their respective ownership
interests, their respective shares of assets, liabilities, revenues, and
expenses associated with the equipment.

     Interest income for the three and six months ended June 30, 1999 was
$155,194 and $265,180, respectively, compared to $100,618 and $197,442 for the
same periods in 1998. Generally, interest income is generated from the temporary
investment of rental receipts and equipment sale proceeds in short-term
instruments. Interest income in 1999 and 1998 includes interest earned on
proceeds resulting from the issuance of Class B Interests. Future interest
income will fluctuate as a result of changing interest rates, the collection of
lease revenue and the proceeds from equipment sales, among other factors.

     The Trust received $261,116 in 1999 as a breakage fee from a third-party
seller in connection with a transaction for new investments that was canceled by
the seller in the first quarter of 1999. This amount is reflected as Other
Income on the accompanying Statement of Operations for the six months ended June
30, 1999.

     During the three and six months ended June 30, 1999, the Trust sold
equipment having a net book value of $11,807 and $4,198,901 to existing lessees
and third parties. These sales resulted in a net gain, for financial statement
purposes, of $329,688 and $474,303, respectively.

     During the three and six months ended June 30, 1998, the Trust sold
equipment having a net book value of $285,905 and $452,310 to existing lessees
and third parties. These sales resulted in a net gain, for financial statement
purposes, of $106,744 and $90,033, respectively.

     It cannot be determined whether future sales of equipment will result in a
net gain or a net loss to the Trust, as such transactions will be dependent upon
the condition and type of equipment being sold and its marketability at the time
of sale. In addition, the amount of gain or loss reported for financial
statement purposes is partly a function of the amount of accumulated
depreciation associated with the equipment being sold.

     The ultimate realization of residual value for any type of equipment is
dependent upon many factors, including EFG's ability to sell and re-lease
equipment. Changing market conditions, industry trends, technological advances,
and many other events can converge to enhance or detract from asset values at
any given time. EFG attempts to monitor these changes in order to identify
opportunities which may be advantageous to the Trust and which will maximize
total cash returns for each asset.

     The total economic value realized for each asset is comprised of all
primary lease term revenue generated from that asset, together with its residual
value. The latter consists of cash proceeds realized upon the asset's sale in
addition to all other cash receipts obtained from renting the asset on a
re-lease, renewal or month-to-

month basis. The Trust classifies such residual rental payments as lease
revenue. Consequently, the amount of gain or loss reported in the financial
statements is not necessarily indicative of the total residual value the Trust
achieved from leasing the equipment.

     Depreciation expense for the three and six months ended June 30, 1999 was
$195,939 and $518,704, respectively, compared to $589,271 and $1,246,030 for the
same periods in 1998. For financial reporting purposes, to the extent that an
asset is held on primary lease term, the Trust depreciates the difference
between (i) the cost of the asset and (ii) the estimated residual value of the
asset on a straight-line basis over such term. For purposes of this policy,
estimated residual values represent estimates of equipment values at the date of
primary lease expiration. To the extent that an asset is held beyond its primary
lease term, the Trust continues to depreciate the remaining net book value of
the asset on a straight-line basis over the asset's remaining economic life.

     Interest expense was $12,544 and $25,501 or 3.6% and 3.8% of lease revenue
for the three and six months ended June 30, 1999, respectively, compared to
$19,962 and $43,447 or 3.4% and 2.8% of lease revenue for the same periods in
1998. Interest expense in future periods is expected to decline as the principal
balance of notes payable is reduced through the application of rent receipts to
outstanding indebtedness. However, to the extent that reinvestment assets are
acquired using financing, future interest expense could increase.

     Management fees were $17,784 and $33,606 for the three and six months ended
June 30, 1999, respectively, compared to $29,109 and $76,727 for the same
periods in 1998. Management fees are based on 5% of gross lease revenue
generated by operating leases and 2% of gross lease revenue generated by full
payout leases. Management fees also include a 1% management fee on non-equipment
investments, excluding cash.

     Operating expenses consist principally of administrative charges,
professional service costs, such as audit and legal fees, as well as
printing, distribution and remarketing expenses. Collectively, operating
expenses were $119,377 and $370,432 for the three and six months ended June
30, 1999, respectively, compared to $188,099 and $246,709 for the same
periods in 1998. Operating expenses were higher during the six months ended
June 30, 1999 principally as a result of costs incurred of approximately
$191,000 related to the repair and remarketing of an aircraft formerly leased
to Alaska Airlines, Inc. in which the Trust held an interest. In addition,
operating expenses in 1999 include an adjustment for 1998 actual
administrative and third party costs of approximately $46,000. The overall
increase from 1998 to 1999 was partially offset by legal expenses accrued
during the six months ended June 30, 1998 related to the Class Action Lawsuit
described in Note 8 to the financial statements. The amount of future
operating expenses cannot be predicted with certainty; however, such expenses
are usually higher during the acquisition and liquidation phases of a trust.
Other fluctuations typically occur in relation to the volume and timing of
remarketing activities.

LIQUIDITY AND CAPITAL RESOURCES AND DISCUSSION OF CASH FLOWS

     The Trust by its nature is a limited life entity. As an equipment leasing
program, the Trust's principal operating activities derive from asset rental
transactions. Accordingly, the Trust's principal source of cash from operations
is provided by the collection of periodic rents. These cash inflows are used to
satisfy debt service obligations associated with leveraged leases, and to pay
management fees and operating costs. Operating activities generated net cash
inflows of $1,272,513 and $2,262,547 for the six months ended June 30, 1999 and
1998, respectively. Future renewal, re-lease and equipment sale activities will
cause a decline in the Trust's primary-term lease revenues and corresponding
sources of operating cash. Overall, expenses associated with rental activities,
such as management fees, and net cash flow from operating activities also will
decline as the Trust experiences a higher frequency of remarketing events.

                          PART I. FINANCIAL INFORMATION


     The Trust's equipment is leased by a number of creditworthy,
investment-grade companies and, to date, the Trust has not experienced any
material collection problems and has not considered it necessary to provide an
allowance for doubtful accounts. Notwithstanding a positive collection history,
there is no assurance that all future contracted rents will be collected or that
the credit quality of the Trust's lessees will be maintained. Collection risk
could increase in the future, particularly as the Trust remarkets its equipment
and enters re-lease agreements with different lessees. The Managing Trustee will
continue to evaluate and monitor the Trust's experience in collecting accounts
receivable to determine whether a future allowance for doubtful accounts may
become appropriate.

     Cash expended for asset acquisitions and cash realized from asset disposal
transactions are reported under investing activities on the accompanying
Statement of Cash Flows. During the six months ended June 30, 1999, the Trust
expended $1,212,000 to acquire its investment in Kirkwood (see Note 5 for
discussion of this transaction). During the six months ended June 30, 1999, the
Trust realized net cash proceeds from asset disposals of $4,673,204 compared to
$542,343 for the same period in 1998. Sale proceeds in 1999 include $4,619,262
related to the Trust's 39.59% interest in a McDonnell Douglas MD-82 aircraft
formerly leased to Alaska Airlines, Inc. which was sold in January 1999. Future
inflows of cash from asset disposal transactions will vary in timing and amount
and will be influenced by many factors including, but not limited to, the
frequency and timing of lease expirations, the type of equipment being sold, its
condition and age, and future market conditions.

     The Trust obtained long-term financing in connection with certain equipment
leases. The repayments of principal related to such indebtedness are reported as
a component of financing activities. Each note payable is recourse only to the
specific equipment financed and to the minimum rental payments contracted to be
received during the debt amortization period (which period generally coincides
with the lease rental term). As rental payments are collected, a portion or all
of the rental payment is used to repay the associated indebtedness. In future
periods, the amount of cash used to repay debt obligations will decline as the
principal balance of notes payable is reduced through the collection and
application of rents. Notwithstanding the foregoing, the Trust has a balloon
payment obligation of $282,421 in 2003, at the expiration of the primary lease
term related to its interest in an aircraft leased to Reno Air, Inc.

     At June 30, 1999, the Trust was due aggregate future minimum lease payments
of $1,341,566 from contractual lease agreements (see Note 3 to the financial
statements), a portion of which will be used to amortize the principal balance
of notes payable of $720,206 (see Note 7 to the financial statements).
Additional cash inflows will be realized from future remarketing activities,
such as lease renewals and equipment sales, the timing and extent of which
cannot be predicted with certainty. This is because the timing and extent of
equipment sales is often dependent upon the needs and interests of the existing
lessees. Some lessees may choose to renew their lease contracts, while others
may elect to return the equipment. In the latter instances, the equipment could
be re-leased to another lessee or sold to a third party. Accordingly, as the
Trust matures and a greater level of its equipment assets become available for
remarketing, the cash flows of the Trust will become less predictable. In
addition, the Trust will have cash needs to satisfy interest on indebtedness and
to pay management fees and operating expenses. Ultimately, the Trust is expected
to meet its future disbursement obligations and to distribute any excess of cash
inflows over cash outflows to the Participants in accordance with the Trust
Agreement. However, several factors, including month-to-month lease extensions,
lessee defaults, equipment casualty events, and early lease terminations could
alter the Trust's anticipated cash flows as described herein and in the
accompanying financial statements and result in fluctuations to the Trust's
periodic cash distribution payments.

     It is the intention of the Managing Trustee to maintain a cash distribution
level that is consistent with the operating cash flows of the Trust and to
optimize the long-term value of the Trust. A distribution level that is higher
than the Trust's operating cash flows could compromise the Trust's working
capital position, as well as its ability to refurbish or upgrade equipment in
response to lessee requirements or other market circumstances. Class A
distributions have been maintained at an annualized rate of $1.64 per Class A
Interest since October 1996. Class B distributions were set at an annualized
distribution rate of $0.66 per Class B Interest commencing July 18, 1997 and
decreased to an annualized distribution rate of $0.47 per Class B Interest in
August 1998

following the Class B Capital Distribution paid at that time. Future
distributions with respect to Class B Interests will be subordinate to certain
distributions with respect to Class A Interests.

     Cash distributions to the Managing Trustee, the Special Beneficiary and the
Beneficiaries are declared and generally paid within 45 days following the end
of each calendar month. The payment of such distributions is presented as a
component of financing activities. For the six months ended June 30, 1999, the
Trust declared total cash distributions of $1,260,624, including the special
distribution described below. Of the total distributions, the Beneficiaries were
allocated $1,187,842 ($950,466 to Class A Beneficiaries and $237,376 to Class B
Beneficiaries); the Special Beneficiary was allocated $64,914, and the Managing
Trustee was allocated $7,868.

     In July 1999, the Trust distributed $500,709, including legal fees of
$26,913 paid to Plaintiffs' counsel, as a special cash distribution in
connection with the settlement of the Class Action Lawsuit described in Note 8
to the financial statements.

     Cash distributions paid to the Participants consist of both a return of and
a return on capital. Cash distributions do not represent and are not indicative
of yield on investment. Actual yield on investment cannot be determined with any
certainty until conclusion of the Trust and will be dependent upon the
collection of all future contracted rents, the generation of renewal and/or
re-lease rents, and the residual value realized for each asset at its disposal
date. Future market conditions, technological changes, the ability of EFG to
manage and remarket the assets, and many other events and circumstances, could
enhance or detract from individual asset yields and the collective performance
of the Trust's equipment portfolio.

     In the future, the nature of the Trust's operations and principal cash
flows gradually will shift from rental receipts to equipment sale proceeds as
the Trust matures and change as a result of potential new investments not
consisting of equipment acquisitions. As this occurs, the Trust's cash flows
resulting from equipment investments may become more volatile in that certain of
the Trust's equipment leases will be renewed and certain of its assets will be
sold. In some cases, the Trust may be required to expend funds to refurbish or
otherwise improve the equipment being remarketed in order to make it more
desirable to a potential lessee or purchaser. The Trust's Advisor, EFG, and the
Managing Trustee will attempt to monitor and manage these events in order to
maximize the residual value of the Trust's equipment and will consider these
factors, in addition to new investment activities and the collection of
contractual rents, the retirement of scheduled indebtedness, and the Trust's
future working capital requirements, in establishing future cash distribution
rates.

     During the past year, the Managing Trustee has evaluated and pursued a
number of potential new investments, several of which the Managing Trustee
concluded had market returns that it believed were less than adequate given the
potential risks. Most transactions have involved the equipment leasing, business
finance and real estate development industries. Although the Managing Trustee
intends to continue to evaluate additional new investments, it is considering
returning a portion of the Trust's capital to the Trust Beneficiaries in the
event that suitable reinvestment transactions are not identified.

     In accordance with the Trust Agreement, upon the dissolution of the Trust,
the Managing Trustee will be required to contribute to the Trust an amount equal
to any negative balance which may exist in the Managing Trustee's tax capital
account. At December 31, 1998, the Managing Trustee had a positive tax capital
account balance. No such requirement exists with respect to the Special
Beneficiary.
